Instructions

Season Beef:
Pat the chuck roast dry and season all sides with kosher salt and black pepper.

Heat olive oil in a large skillet over medium-high heat. Sear the roast on all sides until browned (about 3 to 4 minutes per side). Transfer to the slow cooker.
Add Vegetables:

Mix Liquids and Herbs:
In a bowl, whisk together beef broth, tomato paste, Worcestershire sauce, thyme, rosemary, and bay leaves. Pour this mixture over the roast and vegetables.
Slow Cook:
Cover and cook on low for 8 hours, until the beef is fork-tender.

About 40 minutes before serving, place potatoes in a large pot and cover with cold water. Add salt, bring to a boil, reduce heat, and simmer until very tender (15 to 20 minutes). Drain, return potatoes to the pot, add butter and milk, then mash until smooth and creamy. Season with salt and pepper; add additional milk if needed.

Remove roast from the slow cooker and let rest for 5 minutes. Discard bay leaves. Shred or slice the beef as desired.

Recipe FAQ

How do I ensure the beef is tender?

Slow cooking the chuck roast on low for 8 hours breaks down connective tissue, resulting in tender, fork-ready meat.

What vegetables are best for this dish?

Carrots, celery, and sliced onions add natural sweetness and depth, balancing the savory flavors of the beef.

Can I use a different cut of beef?

Chuck roast is ideal for slow cooking due to its marbling; other cuts like brisket can work but may require adjustments in cooking time.

How to make the gravy thicker?

Remove half a cup of cooking liquid, whisk with cornstarch, return to the pot, and cook on high for 10 minutes until thickened.

What type of potatoes are recommended?
